Should I Get the Sony a7R III or the a7R II?

With the recent release of the Sony a7R III, many may be wondering, "Should I get the a7R III or get the less expensive a7R II instead?" That's a very fair question, and that's why we're going to be looking at how these two MILCs (Mirrorless Interchangeable Lens Cameras) stack up against one another.

  • USB 3.1 Gen 1 Type-C port vs. USB 2.0
  • Anti-flicker shutter timing vs. N/A
  • Built-in Bluetooth, Wi-Fi (w/ftp) & NFC vs. Wi-Fi & NFC only
  • Customizable My Menu
  • Improved peaking, Focus magnification with AF support, Rating, Display continuous shooting group
Primary Advantages of the Sony a7R II over the Sony a7R III
 
  • Lower cost
  • Slightly smaller size, lighter weight: 5.0 x 3.8 x 2.4" (126.9 × 95.7 x 60.3mm), 22.0 oz (625g) vs. 5.0 x 3.88 x 3.0" (126.9 x 95.6 x 73.7mm), 23.2 oz (657g)
Who should opt for the Sony a7R III?
 
Those who wish to capture high resolution sports imagery will immediately appreciate the Sony a7R III's twice-as-fast burst rate (10 fps vs. 5), image grouping display, upgraded AF system and [possibly] the new anti-flicker shutter timing (it may work better under some conditions than it worked in our tests). Those using the a7R III for professional filmmaking will likely benefit from the ability to record 1080p video at 120 fps, the upgraded AF, improved peaking and the S-LOG 3 and HLG (Hybrid Log Gamma) Picture Profiles.
 
Wedding photographers will enjoy the added security of the a7R III's dual memory card slots, and sharing images immediately on social media will be made easier with built-in Bluetooth.
 
Regardless of one's specialty, the upgraded IBIS system providing an extra stop of assistance to help keep images sharp will surely be appreciated by almost all photographers. The same sentiment holds true for the a7R III's increased battery life.
 
Who should opt for the Sony a7R II?
 
As is typical of successor vs. predecessor camera comparisons, the primary reason to recommend the purchase of a camera's predecessor – in this case, the Sony a7R II – is the older camera's lower cost. And in this case, the trend continues, with the a7R II weighing in with a 25% discount (with instant rebates) compared to the a7R III.
 
Landscape, architecture/real estate and studio photographers, in particular, who don't necessarily need a better AF system or a faster burst rate, will have fewer reasons to invest in the a7R III's upgraded features as the a7R II's sensor provides similar, high image quality. That said, the brighter viewfinder and longer battery life of the a7R III will be welcomed even by these groups.
